The review addresses and highlights the main results of research on physicohemical properties single-phase composite materials based transition metal oxides in relation to their practical application as electrode for symmetrical solid oxide fuel cells. electronic structures thermodynamic stability with perovskite structure are discussed. A detailed consideration is given thermal behaviour, chemical stability, electrical conductivity electrochemical a broad range iron-, chromium-...
K x Ln 5− Mo 3 O 16− y F (Ln = La, Pr, Nd) compositions were first synthesized. The conductive properties have been widely studied using a combination of theoretical and experimental approaches. total conductivity reaches ∼10 −2 S cm −1 at 800 °C.
A combination of the unique porous structure and physical chemical properties anodic aluminum oxide (AAO) makes it widely used in cutting-edge areas materials science nanotechnology. Selenic acid electrolyte provides ability to obtain AAO with low porosity high optical transparency thus is promising for preparation photonic crystals (PhCs). Here, we show influence crystallographic orientation Al on electrochemical oxidation rate 1 M H2SeO4 as well growth rate, porosity, effective refractive...
In the present work, extensive study of ionic conductors with pyrochlore and fluorite structure in Gd2O3–HfO2 system are carried out. Gd2Hf2O7 Gd2.1Hf1.9O6.95, Gd2.16Hf1.84O6.92, Gd2HfO5 solid solutions known...
Compounds of the nominal composition NaLa 4 Mo 3 O 15 F 1– x Cl ( = 0–0.7) have been obtained as ceramics and single crystals. Their physical properties crystal structure studied in temperature range 293–1050 K.
Sm2-xCaxZr2O7-x/2 (x = 0, 0.05, 0.1) and Gd2-xCaxZr2O7-x/2 mixed oxides in a pyrochlore-fluorite morphotropic phase region were prepared via the mechanical activation of oxide mixtures, followed by annealing at 1600 °C. The structure solid solutions was studied X-ray diffraction refined Rietveld method, water content determined thermogravimetry (TG), their bulk grain-boundary conductivity impedance spectroscopy dry wet air (100-900 °C), total measured as function oxygen partial pressure...
Electrical transport in polycrystalline rare earth oxymolybdates Ln2MoO6 (Ln = La, Pr, and Nd) was investigated using theoretical experimental methods. The approach consisted of geometrical–topological analysis, bond valence site energy (BVSE) simulation, density functional theory (DFT) calculations. BVSE modeling revealed that ionic conductivity can occur only by oxygen migration. DFT calculations showed the roughly equal value barriers to migration all (less than 0.85 eV)....
